This heavenly trifle dessert combines the rich flavors of chocolate cake, caramel, whipped cream, and toffee for an indulgent treat that's perfect for special occasions or when you want to impress guests.

I first made this trifle for my sister's birthday dinner when I needed something spectacular but didn't have time for complicated baking. The moment I brought it to the table, everyone's eyes widened, and it's now requested at nearly every family gathering.
Ingredients
- Devil's Food cake mix: Plus ingredients called for on box creates the perfect chocolate base that balances the sweetness of the other components
- Sweetened condensed milk: Adds moisture and a creamy richness that transforms the cake completely
- Whipped cream: Provides light, airy layers that contrast with the dense cake
- Caramel syrup: Creates pockets of sweet, buttery goodness throughout each bite
- Heath English Toffee Bits: Deliver a satisfying crunch and butterscotch flavor
- King-Sized Heath bar: For the final decorative touch that hints at the toffee goodness inside
Step-by-Step Instructions
- Prepare the Cake:
- Follow the box instructions exactly, paying attention to proper mixing technique. A moist cake is crucial as it will absorb the sweetened condensed milk. Use room temperature eggs and don't overmix the batter to ensure the cake stays tender.
- Cut the Cake into Squares:
- Wait until the cake is cool enough to handle but still warm. Use a serrated knife to create roughly 1-inch squares. The warm cake will better absorb the sweetened condensed milk, creating that pudding like texture that makes trifles so irresistible.
- Add Sweetened Condensed Milk:
- Pour the entire can of sweetened condensed milk evenly over all the cake pieces, making sure each piece gets some of that sweet goodness. Let it sit for about 5 minutes so the milk fully penetrates the warm cake, creating a rich, moist foundation.
- First Layer in the Trifle Bowl:
- Place one third of the milk soaked cake pieces in an even layer across the bottom of your trifle bowl. Press them gently to create a relatively flat surface for the remaining ingredients to rest upon. This base layer sets the structure for the entire dessert.
- Add the Whipped Cream, Caramel, and Toffee:
- Dollop one third of the whipped cream over the cake layer and spread gently with an offset spatula. Drizzle one third of the caramel syrup in a crisscross pattern for even distribution. Sprinkle one third of the toffee bits generously over the entire surface, making sure they reach the edges.
- Repeat the Layers:
- Create two more complete layers following the same pattern. For the middle layer, press down slightly to eliminate air pockets. For visual appeal, allow some of the toffee bits and caramel to touch the sides of the glass bowl so they're visible from the outside.
- Top with Crushed Heath Bars:
- Place the Heath bar in a sealed plastic bag and crush with a rolling pin until you have a mix of fine crumbs and small chunks. Sprinkle this over the final layer of whipped cream, concentrating more in the center for height and visual impact.
- Refrigerate:
- Cover the trifle carefully with plastic wrap and refrigerate for at least 2 hours, though overnight is even better. This resting time allows the flavors to meld together and the textures to harmonize into a cohesive dessert.

The caramel syrup is truly the secret ingredient that makes this trifle special. I discovered this by accident when I was short on chocolate sauce once and used caramel instead. The way it creates these pockets of sweet, buttery goodness throughout the dessert transforms it from good to unforgettable.
Make It Your Own
Everyone has their own preference for the perfect ratio of components in a trifle. Feel free to adjust the amounts of caramel, whipped cream, or toffee bits to suit your taste. Some of my family members prefer extra caramel, while others like more toffee bits for additional crunch. The beauty of this dessert is that it's forgiving and adaptable.
Storage Tips
This trifle holds up beautifully in the refrigerator for up to 3 days. The cake will continue to soften and the flavors will intensify over time. Cover with plastic wrap directly touching the surface to prevent the whipped cream from absorbing other refrigerator odors. For best visual presentation, add the final Heath bar topping just before serving if making far in advance.
Ingredient Substitutions
This recipe is remarkably versatile. If you prefer a lighter option, angel food cake works beautifully instead of Devil's Food. Not a fan of Heath bars? Butterfinger, Snickers, or even Oreo cookies make excellent alternatives. For a boozy adult version, consider adding 3 tablespoons of Baileys or Kahlúa to the sweetened condensed milk before pouring over the cake.

The magic of this trifle is in its ability to bring people together. There's something about a beautiful dessert shared among friends and family that creates lasting memories even beyond the delicious taste.
